TL;DR: It is argued that a similar general framework of weaknesses and strengths is likely to have operated in the past, and thus have been of similar relevance in defining and promoting the ecological achievements of the fossil pteridophytes in relation to selection pressures and consequent adaptations.

TL;DR: The majority of ferns in Eurasia grew under warm (subtropical to tropical) conditions in moist environments, including peat-forming swamps, freshwater marshes, riverbanks and understorey vegetation in forests.

TL;DR: The Latin American Pollen Database (LAPD) as mentioned in this paper provides a taxonomic description of the parent taxa responsible for producing the pollen in sedimentary records from Latin American regions.

TL;DR: Karsten et al. as mentioned in this paper studied the late Quaternary history of fossil spruces in southern Europe (Picea abies (L.) Karsten and Picea omorika (Pancic) Purkyne) based on 163 selected pollen, charcoal and macrofossil records.

TL;DR: It is concluded that fossil pollen can not be ascribed to recent and native taxa that produce the same kind of pollen and should be defined as a limitative collection of morphological properties.

TL;DR: The ecology of Cainozoic ferns is documented (excluding that based only on nearest living relatives). Free-floating water Ferns (of the modern genera Azolla and Salvinia ) are widespread in the Cainogene as mentioned in this paper.

TL;DR: Pollen and charcoal analysis on marine sediment core Fr10/95, GC-17 provides a record of vegetation, fire and climate change for the last 100 ka, with a hiatus from 64 to 46 ka, for the Cape Range Peninsula, Western Australia as discussed by the authors.

TL;DR: In this paper, the authors investigate pollen-vegetation relationships in samples from soil surfaces, animal dung, and sediments in depressions or basins that, in theory, should have pollen spectra that are comparable to those from sedimentary basins elsewhere.

TL;DR: V virtually all of the life histories and body plans that characterized Paleozoic ferns would reappear independently, plus some new kinds of organization and ecology, emphasizing the great evolutionary flexibility and responsiveness of fern-like construction and reproductive biology.

TL;DR: The terpenoid composition of three fossil resins from macrofossils of Cretaceous and Tertiary conifers has been analyzed by gas chromatography–mass spectrometry (GC–MS) and proved to be valuable chemosystematic markers for fossil conifer once they are adequately preserved.

TL;DR: Two sediment cores (Maxus 4 and Maxus 1) were obtained from lowland wetlands situated in the highly diverse rain forests of the western Amazon basin, Ecuador, and analyzed for fossil pollen, charcoal and loss-on-ignition.

TL;DR: The Australian and North American diversity data for free-sporing plants, gymnosperms and angiosperms are broadly similar, however, Schizaeaceae and Gleicheniaceae display different trends during the mid-Cretaceous, increasing in diversity in the Australian palynofloras, but decreasing in North America.

TL;DR: The stem anatomy and organization of new anatomically preserved Grammatopteris fern specimens are described from the Permian of the Maranhao Basin (NE Brazil), thought to be of considerable importance or a link in the origin and early development of Osmundaceae.

TL;DR: An initial phylogenetic analysis of living species using plastid rbcL nucleotide sequence data is conducted, and fossil evidence indicates that subgeneric groups within the Anemia/Mohria clade are comparatively ancient, originating during the Early Cretaceous.

TL;DR: In this paper, a comparative analysis of two techniques used for the extraction of fossil phytoliths from sediments is presented, as well as the advantages and disadvantages of their use.

TL;DR: In this article, a high-resolution pollen analysis has been carried out on the Lupoaia section (SW Romania) in order to check whether the repetitive clay-lignite alternations correspond to cyclic changes in climate.

TL;DR: A reinvestigation of the palynology of Recent and sub-Recent Orinoco Delta sediments complements the work by Jan Muller concerning the taxonomy and diversity of pollen grains as discussed by the authors.

TL;DR: Li et al. as discussed by the authors identified an autochthonous/hypoautochTHonous fern community from the upper part of the Hsiangchi Formation in Zigui, Hubei.

TL;DR: In this paper, a comparison of the pollen record of several cores at different distances to palaeo-vegetation units enabled reconstruction of changing vegetation patterns during the Weichselian Lateglacial and Early Holocene in and around the Endinger Bruch (Vorpommern, NE Germany).

TL;DR: Pollen analysis from archaeological sequences in the Lago Argentino area (Southwest Santa Cruz province, Argentina) are used to infer vegetation and climatic changes during the Holocene as discussed by the authors.

TL;DR: The Chengzihe Formation of Jixi, China is considered Hauterivian or early Barremian in age as discussed by the authors, and the diversity of angiosperms found, the small size of the leaves and the associated reproductive material probably attached to an angiosperm leaf.

TL;DR: In this paper, the authors demonstrate a succession of miospore assemblages from closely sampled layers that have been stratigraphically dated as Ludlow-middle Pridoli and early Lochkovian by chitinozoans and acritarchs.

TL;DR: The co-occurrence (in fine-grained sediments in coal-bearing strata) of large and/or delicate, relatively complete fronds, fertile and sterile material and rhizomes with stipes, shows that the majority of these ferns grew in moist habitats close to their depositional setting.

TL;DR: The composition and main biohorizons of Western Gondwanan regions are reviewed and compared to corresponding miospore zones of Southern Euramerica as discussed by the authors, where the most significant taxa are recorded in the main investigated basins of North Africa, Saudi Arabia and Brazil.

TL;DR: In this article, the authors examined the pollen of a grand total of 460 collections representing 372 species from 112 of the 116 assigned genera of the Acalyphoideae.

TL;DR: The discovery of a dominant Glossopteris flora, including petrified leaf fragments, Vertebraria and Araucarioxylon-type wood, along with the absence of Dicroidium, suggests a latest Permian age as discussed by the authors.

TL;DR: The hypothesis is that the Early Permian flora of the northern Cathaysian realm represents the continued evolution of wetland Euramerican-type coal-swamp floras, and as such is likely to present a model for evolutionarily driven floral change as opposed to the climatically driven floral changes observed in the Euramerica flora after the demise of coal-Swamp environments.

TL;DR: Tertiary leaf compressions of a Ginkgo plant with cuticle displaying all taxonomically important epidermal features are reported for the first time from Greece, and for the Mediterranean area as a whole, and a high variability in the degree of papillosity of subsidiary cells of stomata is observed.

TL;DR: In this paper, the authors used plant macrofossil, colorimetric humification and testate amoebae analyses to reconstruct proxy climate records from two raised peat bogs in the Scottish Borders, Raeburn Flow and Bell's Flow.

TL;DR: In this article, a large number of acritarchaearch and prasinophyte phycomata assemblages were recovered from the late Silurian to Lower Devonian strata of well A161 in western Libya, and four distinct acritarchy biozones were recognized, based on the stratigraphic distribution of 156 species.
